Compelled by McKinney's entrepreneurial culture, lust for innovation and independent spirit, John joined the leadership ranks in 2005 from Publicis. In 2012, John was named president of the agency. “There is potential in everything and everybody: brands, people, teams, departments,” he said. “Creating an environment where that's possible is the most important thing to me.”

He's fond of saying that creativity is the most effective economic multiplier. Creativity in action, that is: “The entrepreneurial spirit at the agency means that we fall in love with ideas and don't stop until we make them happen. Passion and action are what define an entrepreneur.” With a personal brand grounded in the color purple, John is also a quotaholic. Hang around long enough, and you'll hear him channel Dr. Wayne Dyer.
